This commit expands the documentation of the `Func` type as well as
updating the Rust embedding tutorial with more recent APIs. I wanted to
also leave space in the Rust tutorial to get more ambitious over time
with what it's documenting, but I stopped around here, curious to see
what others think about it!
This is a rebase of [1]. In the long term, we'll want to simplify these
analysis passes. For now, this is simple and will reduce the number of
instructions processed in certain cases.

* Reuse std::io::Error for raw *nix errno
This commit removes custom `yanix::Errno` and instead (as was
previously suggested) reuses `std::io::Error` to generate and wrap
raw *nix errno value.
* Update wasi-common to use new Yanix error type
This commit updates `wasi-common` to use new way of handling raw
OS error in `yanix`; i.e., via re-use of `std::io::Error` instead
of a custom `Errno` enum.
* Fix formatting
* Unwrap if io::Error created from raw OS error
This commit calls `unwrap` on `err` if that one was created via
`io::Error::last_os_error()`. It also refactors error matching
in several syscalls on the BSD platform (mainly).
This commit removes the two fuzz targets that we imported from cranelift
when cranelift merged in. These have both uncovered a few issues in the
fuzz targets themselves, for example:
* `translate_module` - this doesn't verify the wasm is valid a head of
time and cranelift is known to panic on translating invalid wasm
modules. We also already do a lot of fuzzing of translation of wasm
modules, so this isn't necessarily buying us anything over what we're
already fuzzing.
* `reader_parse_test` - discovered in #1205 we already found some "bugs"
in this but it may not necessarily rise to the level of "needs to be
run on oss-fuzz for us to find more bugs" yet. It looks like this is
still somewhat internal so we can re-enable when we've got folks to
fix the fuzz bugs coming in.
Closes#1205
* Add a wasmtime-specific `wasmtime_wat2wasm` C API
This commit implements a wasmtime-specific C API for converting the text
format to the binary format. An upstream spec issue exists for adding
this to the C API, but in the meantime we can experiment with our own
version of this API and use it in the C# extension, for example!
Closes#1000
* Reorder arguments
* Use wasm_byte_vec_t for input `*.wat`
* Mark wat input as const
* Return an error message and use `fixed`
* Actually include the error message
* Use `fixed` in `Module.cs` as well
* rename PassiveElemIndex to ElemIndex and same for PassiveDataIndex (#1411)
* rename PassiveDataIndex to DataIndex
* rename PassiveElemIndex to ElemIndex
* Apply renamings to wasmtime as well
* Run rustfmt

wasmtime is covered by oss-fuzz which should cover large swaths of
cranelift as well, so let's remove that from CI and add it back later if
it's necessary.
